Publication number: 20140284937Abstract: The system is a drilling bearing device. The device includes an outer body structure, and inner body structure, and a loading structure. The inner body structure is disposed at least partially within the outer body structure. The inner body structure moves relative to the outer body structure. The loading structure is disposed between the outer body structure and the inner body structure. The loading structure facilitates adjustment of a position of the inner body structure relative to the outer body structure relative to the outer body structure resulting from mechanical wear in the device. The loading structure substantially prevents displacement of the inner body structure relative to the outer body structure in response to a reciprocating displacement to maintain a substantially constant relative location.Type: ApplicationFiled: March 20, 2014Publication date: September 25, 2014Applicant: Oscilla Power Inc.Inventors: James H.

Patent number: 8414752Abstract: A mixed potential NOx sensor apparatus for measuring the total NOx concentration in a gas stream is disclosed. The NOx sensing apparatus comprises a multilayer ceramic structure with electrodes for sensing both oxygen and NOx gas concentrations and includes screen-printed metallized patterns that function to heat the ceramic sensing element to the proper temperature for optimum performance. This design may provide advantages over the existing technology by miniaturizing the sensing element to provide potentially faster sensor light off times and thereby reduce undesired exhaust gas emissions. By incorporating the heating source within the ceramic sensing structure, the time to reach the temperature of operation is shortened, and thermal gradients and stresses are minimized. These improvements may provide increased sensor performance, reliability, and lifetime.Type: GrantFiled: November 2, 2009Date of Patent: April 9, 2013Assignee: EmiSense Technologies, LLCInventors: Balakrishnan G.

Publication number: 20090038297Abstract: Ceramic catalytic compositions, systems, and methods for oxidizing, converting and/or removing NOxgas species present in gas streams such as exhaust gases are provided. The catalysts of the invention oxidize the nitrogen monoxide (NO) in gas streams to nitrogen dioxide (NO2), which may be adsorbed by a metal oxide or other NO2 adsorber. Catalysts suitable for use in systems of the present invention include ceramic oxides, mixtures of ceramic oxides, complex ceramic oxides, and mixtures of complex ceramic oxides. Such catalysts are shown herein to successfully achieve an NO-NO2 equilibrium gas composition at temperatures as low as 275° C. In addition, by using the catalyst with an NO2 adsorber, greater than 95% removal of combined NO and NO2 from the gas stream has been successfully demonstrated. Further, specific strategies have been identified to regenerate the catalyst system and restore performance after prolonged exposure to species such as sulfur dioxide (SO2).Type: ApplicationFiled: September 1, 2005Publication date: February 12, 2009Applicant: CERAMATEC , Inc.Inventors: Balakrishnan Nair, Sai Bhavaraju, Jesse Nachlas, James Steppan

Patent number: 7442555Abstract: A mixed potential sensor device and methods for measuring total ammonia (NH3) concentration in a gas is provided. The gas is first partitioned into two streams directed into two sensing chambers. Each gas stream is conditioned by a specific catalyst system. In one chamber, in some instances at a temperature of at least about 600° C., the gas is treated such that almost all of the ammonia is converted to NOx, and a steady state equilibrium concentration of NO to NO2 is established. In the second chamber, the gas is treated with a catalyst at a lower temperature, preferably less than 450° C. such that most of the ammonia is converted to nitrogen (N2) and steam (H2O). Each gas is passed over a sensing electrode in a mixed potential sensor system that is sensitive to NOx. The difference in the readings of the two gas sensors can provide a measurement of total NH3 concentration in the exhaust gas. The catalyst system also functions to oxidize any unburned hydrocarbons such as CH4, CO, etc.Type: GrantFiled: December 22, 2005Date of Patent: October 28, 2008Inventors: Balakrishnan G. Nair, Jesse Nachlas

Publication number: 20080017510Abstract: The present invention is an apparatus for determining NOx concentration of an exhaust gas stream. The apparatus may include an input assembly capable of receiving the exhaust gas and producing a conditioned output gas. The input assembly includes an oxidizing catalyst structure for oxidizing unburned hydrocarbons and gases to higher oxidation states and an equilibrium structure for establishing a steady state equilibrium concentration ratio between NO and NO2, said NO2 concentration between about 0% an about 10% by volume. The apparatus also includes a NOx sensor operably connected to the input assembly for receiving the conditioned output gas of the input assembly. The apparatus also includes an oxygen sensor in operable communication with the NOx sensor, such that the concentration of the NOx present in the exhaust gas can be determined.Type: ApplicationFiled: May 14, 2007Publication date: January 24, 2008Inventors: Balakrishnan Nair, Jesse Nachlas, Michael Middlemas

Patent number: 7217355Abstract: The present invention is a method and apparatus for measuring the total NOx concentration in a gas stream utilizing the principles of a NOx sensor, i.e., mixed potential sensor. The exhaust gas is first conditioned by a catalyst assembly that converts the various species of nitrogen oxide gases present to a fixed steady state concentration ratio of NO2/NO, where NO2 is approximately 0–10% of the total NOx concentration present in the gas exhaust, thereby enabling the NOx sensor to generate a meaningful and reproducible determination of the concentration of total NOx present in the gas being measured. The catalyst assembly also functions to oxidize any unburned combustibles such as CH4, CO, etc., and remove potential contaminants such as SO2.Type: GrantFiled: May 25, 2005Date of Patent: May 15, 2007Assignee: Ceramatec, Inc.Inventors: Balakrishnan G.
